Everyone is not very familiar with the power frequency furnace and the intermediate frequency furnace. After all, it is a widely used equipment in the industry. If we are not engaged in industrial production, we still rarely touch these two kinds of equipment in our life. So, let Kehua introduce them to you next. Power frequency furnace and intermediate frequency furnace 1. Power frequency furnace The power frequency electric furnace can melt and heat the metal, and the heating is uniform and the burning loss is small, which is easy to adjust the composition of the molten iron and has less pollution. However, the power frequency electric furnace melts the cold material slowly, which is not conducive to slag making. The cold furnace needs to start the block, and the production is not flexible enough. Therefore, it is generally used for remelting and heating of metals and alloys. In addition, the power factor of the power frequency electric furnace is low, and a large number of compensation capacitors need to be configured, which also increases the floor space and equipment investment. 2. The intermediate frequency furnace is a power supply device that converts power frequency 50HZ alternating current into intermediate frequency (300HZ and above to 1000HZ), converts three-phase power frequency alternating current into direct current after rectification, and then converts direct current into adjustable intermediate frequency current to supply The intermediate frequency alternating current flowing through the capacitor and the induction coil generates high-density magnetic lines of force in the induction coil, and cuts the metal material contained in the induction coil, generating a large eddy current in the metal material. Power frequency furnace and intermediate frequency furnace 3. Power frequency furnace body structure 1. Furnace body: The furnace body includes induction coils, crucibles, yokes and steel frames and other components. A. Inductor: Made of red copper material, the inductor consists of several sets of coils It is formed in parallel in order to adjust the power and the direction of the molten iron stirring movement. B. Magnetic yoke: It is a yoke made by laminating silicon steel sheets. Function: Constrain the magnetic force lines generated by the induction coil to scatter outward, so that the magnetic force line bundles are concentrated around the induction coil to improve the efficiency of induction heating. And play the role of magnetic shielding. 2. Hydraulic transmission system: the furnace body can be tilted to 95 degrees. 3. Water cooling system: capacitors, sensors and flexible cables all need water cooling, and the humidity of the outlet water should be less than 50 degrees. 4. The working principle of the intermediate frequency furnace The intermediate frequency electric furnace uses the intermediate frequency power supply to establish an intermediate frequency magnetic field, so that the ferromagnetic material generates an induced eddy current and generates heat, so as to achieve the purpose of heating the material. The intermediate frequency electric furnace adopts 200-2500Hz intermediate frequency power supply for induction heating, smelting and heat preservation. The intermediate frequency electric furnace is mainly used for smelting carbon steel, alloy steel, special steel, and can also be used for smelting and heating of non-ferrous metals such as copper and aluminum. The equipment is small in size and light in weight. Light, high efficiency, low power consumption, fast melting and heating, easy control of furnace temperature, and high production efficiency. After reading the introduction of power frequency furnace and intermediate frequency furnace, do you have any questions? The above content is enough to let you know these two kinds of equipment. They have their own characteristics. Kehua pointed out that they are very important equipment in people's production. .
